HDPE pipe flange is a connection method used to connect HDPE pipes with other pipeline materials or equipment, such as steel pipes, valves, pumps, etc. This method requires the use of HDPE Stub Ends and connects two flanged pipes together with bolts and nuts.
Function
HDPE pipe flange can be placed between the two flanges using a gasket to ensure the tightness of the connection. This connection method is suitable for detachable connections on low-pressure transmission pipelines, especially when it is necessary to connect with cast iron pipes and steel pipes, the flange connection method provides a simple connection solution. The advantages of flange connection include its non-rigid connection, detachability, and good tensile strength, which makes it flexible in engineering applications.
HDPE pipe flange Structure
HDPE pipe flange consists of two flanges with connection holes, sealing gaskets, and several bolts and nuts. This connection method requires not only good sealing, but also the ability to withstand the pressure and temperature fluctuations generated by the fluid in the pipeline.
Types of HDPE pipe flanges
The types of HDPE pipe flanges include butt-jointed flanges, socket-jointed flanges, electric fusion flanges, and hot-melt butt-welding flanges.
The butt-jointed flange is a common type of HDPE flange that connects pipes by butt-jointing to form a tight seal, prevent leakage, and ensure efficient fluid flow within the system. This flange is suitable for a variety of industrial applications, such as oil and gas, petrochemicals, and manufacturing. The socket-jointed flange is another common HDPE flange that connects pipes by socket-jointing. It also has good sealing performance and is suitable for occasions that need to withstand high pressure and corrosive media. Electrofusion flanges and hot-melt butt-welding flanges connect pipes by electric fusion or hot fusion. This connection method can provide reliable sealing and is suitable for various industrial pipeline systems.
Advantages of flange connection
1. Firm and reliable: The flange connection method has extremely high sealing performance, can prevent fluid leakage, can withstand high water pressure and air pressure, and is not prone to loosening during transportation and use.
2. Wide range of applications: Flange connection can connect various pipe materials, such as steel pipes, cast iron pipes, copper pipes, etc., and can also connect pipes of different diameters, with good versatility.
3. Convenient disassembly: Although flange connection is a non-detachable connection method, it is easier to disassemble than other connection methods. It should be noted that you should be careful not to damage the flange during disassembly.
